To all whom it may concern:

Be it known that I, 'SAMUEL H. YANCEY, a citizen of the United States, residin at New York city in the county of New ork e and State of New York, have invented certain new and useful Improvements in Seals for Metal Cans and like Containers; and I do hereby declare the following to be a full, clear, and exact description of the invention,

10 such as will enable others skilled in the art to which it appertains to make and use the same.

The primary object of the present invention is the provision of means for scaling is shipping cans, and which will admit of the subsequent closing of the cans by an ordinary stopper after the seal has been broken.

The can or analogous container is provided with an opening through which the ac same is filled and the contents subsequently drawn 05. A collar, formed with the can, projects therefrom in line with the opening and has its inner wall grooved. The closure consists of a metal cap of such relative size at as to fit snugly within the collar, a portion of the rim or wall of the cap being pressed outwardly into the groove formed in the inner wall of the collar, whereby to prevent displacement of the closure and making it so necessary to cut the crown of the cap when it is required to gain access to the contents of the can.

Other objects and advantages will be apparent and suggest themselves as the nature as of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet difier ent conditions and requirements, various to changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention. I

Referring to the accompanying drawings as forming a part of the application,

pressing a portion thereof outwardly into the groove of the collar,

Figure 3 is a sectional perspective view, the closure being omitted, and

Figure 4 is a view similar to Figure 1 of a modification.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 1 designates the topof a sheet metal or other container in which is formed an opening 2, through which the container is filled and the contents subsequently drawn 0E. A collar 3 pressed outwardly from the top of the can or container in line with the opening 2 therein may be of any construction. A groove 4 is rovided in the inner wall of the collar 3 an extends entirely there around.

The closure for sealing the can or container preferably consists of a sheet metal cap which comprises a crown 5, a wall or rim 6 and an outer flange 7. The closure is of a size to snugly fit within the collar 3 and after being positioned therein, a portion of the wall or rim 6 is pressed outwardly into the groove 4, as indicated at 8, thereby preventing removal of the closure and assuring a tight joint. The outer flange 7 engages the upper edge of the collar 3, thereby limiting the inward movement of the closure when pressed into the collar and assistin materially in preserving a close joint and stifi'ening the closure to prevent its removal. The oove 4 may be at any point in the depth of the collar and, as shown in Figure 4, the groove 4 is located at the inner end of the collar 3 and in the remaining views at a point between the inner and outer ends of the collar.

To open a can or container which has been sealed in accordance with the present invention, it is necessary to cut away the crown 5 of the closure. The can may be subsequently closed by means of an ordinary stopper which may be inserted in the collar 3, or by means of a screw cap which may be fitted to the threaded collar 9, as will be readily understood. The pressing of the gen part 8 of the closure outwardly into the groove 4 may be efi'ected by a beading tool, such as commonly used for expanding the ends of pipes in the head and crown sheet of boilers, or in any preferred way.

What is claimed is:

A. container having a collar about its filling and dispensing opening, a closure for said collar, the closure being of a shape to permit application of a stopper afterpuncture of the closure, said collar at its outer
